Fastener lockup
Locking often occurs on solid parts of stainless steel, aluminium alloys and titanium alloys. These metal alloys have anti-corrosive properties and produce a thin layer of oxide on the metal surface when the surface is damaged. In the case of stainless steel, it is chromium oxide to prevent further deeper rust.
When the stainless steel fastener is locked, the pressure and heat generated between the teeth will destroy and erase the chromium oxide layer between them, causing the metal tooth to directly block/shear, and then be sticking. When the adhesion phenomenon continues to occur, usually no more than one full calliper. The stainless steel fasteners will be completely locked and can no longer be removed or locked.
Understanding the characteristics of stainless steel products and following the correct procedures is the first step to prevent the rigid parts of stainless steel from locking.
